Betelgeuse’s future supernova won’t harm Earth, but close cosmic explosions could strip our ozone, risking life. Gamma-ray ...

NASA detailed the blast in a report on its website. The explosive outburst was detected by NASA’s Fermi Gamma-ray space telescope, the Neil Gehrels Swift Observatory, and the Wind spacecraft.

Gamma rays are the shortest wavelength electromagnetic ... New research shows that Earth’s ionosphere was disturbed for several hours by the blast. Enough energy arrived at Earth to activate ...

When stars explode as supernovas, they can cause serious cosmic carnage. Is Earth in any danger from any nearby stars?

"The gamma-ray burst traveled through intergalactic space at the speed of light for eleven billion years, during which time the Sun and the planets were born." — Timothy Ferris, in the film ...

China and France set off on a mighty explosion toward the universe when they launched the joint Sino-French SVOM mission. Their aim was to study Gamma-ray bursts that coincided with an event where ...

Nine Galactic sources are the highest-energy gamma -ray sources ever detected, which could suggest the presence of Galactic accelerators Disclaimer: AAAS and EurekAlert! are not responsible for ...

Gamma radiation transforms methane into glycine and various other complex molecules. A research team reports in the journal Angewandte Chemie that gamma radiation can transform methane into a diverse ...

That isn’t the only way to measure gamma radiation, though, and [Alan] has a great circuit to measure even relatively weak radiation sources. It uses a very small photodiode, and draws so little ...

While scientists are still debating the excess, one research group has proposed that gamma-ray bursts can be used as a powerful probe to examine the surplus, which could also observe the formation ...

For that, you need something like this gamma-ray spectroscope. Dubbed the Pomelo by [mihai.cuciuc], the detector is a homebrew solid-state scintillation counter made from a thallium-doped cesium ...

Gamma-ray bursts generally occur after the explosion ... study black holes The extremely bright cosmic beams can give off a blast of energy equivalent to over a billion suns.
